The program seeks to develop subsystem technologies that are new and revolutionary in their impact, rather than incremental improvements of existing subsystems. The goal is to advance subsystem technologies from a readiness level of 3 (analytical and experimental critical function and/or characteristic proof of concept) to a readiness level of 5 (component and/or breadboard validation in relevant environment).   Support flight demonstrations of new technologies, capabilities and applications for small spacecraft. The program seeks to demonstrate technologies that are new and capabilities that have not previously been demonstrated in space. The goal is to advance technologies and capabilities from a readiness level of 5 (component and/or breadboard validation in relevant environment) to a readiness level of at least 7 (system prototype demonstration in an operational environment).   Use small spacecraft as platforms for testing and demonstrating technologies and capabilities that might have more general applications in larger-scale spacecraft and systems. The program seeks to contribute to the full range of NASA's science and technology challenges, where demonstrations with small spacecraft can reduce the cost, risk, complexity or time required to advance the state-of-the-art.","programId":65,"responsibleMd":{"organizationId":4875,"organizationName":"Space Technology Mission Directorate","acronym":"STMD","organizationType":"NASA_Mission_Directorate","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"","organizationTypePretty":"NASA Mission Directorate"},"responsibleMdOffice":4875,"stockImageFileId":36659,"title":"Small Spacecraft Technology","manageGaps":false,"acronymOrTitle":"SST"},"acronym":"ISAAC","description":"<p>This project will develop a new subsystem technology for CubeSats. Integrated Solar-Panel Antenna Array for CubeSats (ISAAC) is an efficient, compact, high gain, low power consumption, lightweight, small volume, X-band antenna array with circularly-polarized radiation to support high data rate downlink. The antenna design is optically transparent (i.e. will not compete for valuable surface real estate), modular, and is independent from the solar cells.</p>","benefits":"<p>Today's CubeSat system uses either UHF or S-band communication systems with only up to 3 Mbps downlink. With the proposed X- band antenna, the downlink bit rate will be enhanced to 50 Mbps with reasonable modulation and coding. Due to its high performance, ISAAC will play a key role in the link budget and relaxes dependency on complex ground stations, which will consequently reduce the cost of science mission.</p>","releaseStatus":"Released","status":"Completed","viewCount":617,"destinationType":["Earth"],"trlBegin":5,"trlCurrent":5,"trlEnd":5,"lastUpdated":"01/22/26","favorited":false,"detailedFunding":false,"projectContacts":[{"contactId":388948,"canUserEdit":false,"firstName":"Reyhan","lastName":"Baktur","fullName":"Reyhan Baktur","fullNameInverted":"Baktur, Reyhan","receiveEmail":"Subscribed_User","projectContactRole":"Principal_Investigator","projectContactId":546544,"projectId":91602,"programContactRolePretty":"","projectContactRolePretty":"Principal Investigator"}],"programContacts":[],"leadOrganization":{"organizationId":3116,"organizationName":"Utah State University","acronym":"USU","organizationType":"Academia","city":"Logan","stateTerritoryId":35,"stateTerritory":{"abbreviation":"UT","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Utah","stateTerritoryId":35,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"84322","murepUnitId":230728,"academicDegreeType":"Public_4_year","msiCategories":["Alaska Native and Native Hawaiian Serving Institutions (ANNH)"],"msiData":{"2016":["Alaska Native and Native Hawaiian Serving Institutions (ANNH)"],"2017":["Alaska Native and Native Hawaiian Serving Institutions (ANNH)"]},"setAsideData":[],"projectId":91602,"projectOrganizationId":574380,"organizationRole":"Lead_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Lead Organization","organizationTypePretty":"Academia"},"otherOrganizations":[{"organizationId":3116,"organizationName":"Utah State University","acronym":"USU","organizationType":"Academia","city":"Logan","stateTerritoryId":35,"stateTerritory":{"abbreviation":"UT","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Utah","stateTerritoryId":35,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"84322","murepUnitId":230728,"academicDegreeType":"Public_4_year","msiCategories":["Alaska Native and Native Hawaiian Serving Institutions (ANNH)"],"msiData":{"2016":["Alaska Native and Native Hawaiian Serving Institutions (ANNH)"],"2017":["Alaska Native and Native Hawaiian Serving Institutions (ANNH)"]},"setAsideData":[],"projectId":91602,"projectOrganizationId":574380,"organizationRole":"Lead_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Lead Organization","organizationTypePretty":"Academia"},{"organizationId":4947,"organizationName":"Goddard Space Flight Center","acronym":"GSFC","organizationType":"NASA_Center","city":"Greenbelt","stateTerritoryId":3,"stateTerritory":{"abbreviation":"MD","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Maryland","stateTerritoryId":3,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"20771","projectId":91602,"projectOrganizationId":574379,"organizationRole":"Supporting_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Supporting Organization","organizationTypePretty":"NASA Center"}],"primaryTx":{"taxonomyNodeId":11136,"taxonomyRootId":8817,"parentNodeId":11130,"code":"TX05.2.6","title":"Innovative Antennas","description":"Flight and ground antennas provide more-innovative and more-effective apertures than those currently in operation and provide high efficiency but lower mass-per-unit area and accurate pointing.","exampleTechnologies":"Deployable antennas;
